摘要
运用电化学电位调控浮选理论，对方铅矿石灰乙硫氮体系进行研究。结果表明：在高碱介质中，石灰不仅仅是作为矿浆ｐＨ的调整剂，还表现出对特定的矿浆电位有很好的稳定作用，而这一特定的矿浆电位正是方铅矿的浮选电位；与黄药相比，乙硫氮是方铅矿更好的选择性捕收剂。电位调控浮选在两个矿山的生产实践表明，未加闪锌矿抑制剂，实现了铅锌铁硫化矿的有效浮选分离，其中铅精矿品位分别提高０．７３％和１．８９％，铅的回收率分别提高２．２４％和６．５８％，锌的回收率分别提高４．６３％和４．１９％，同时，两个矿山的每吨原矿药剂成本均下降１０元左右。这一研究成果使电化学调控捕收剂浮选在生产实践中成功应用迈出了一步。
The flotation electrochemistry of the galenalimediethyldithiocarbamate system was studied by theory of potential adjustment flotation. The results showed that, in strong alkaline media, lime was regulator of pH, it could stabilize special potential very well , and this special potential was exactly flotation potential of galena. Diethyldithiocarbamate was more better selective collector than Xanthate on galena. Furthermore the separation practice in Lechang LeedZinc Mine, Guangdong, and Beishan LeadZinc Mine, Guangxi, showed that, without adding zincdepressants, leadzinciron sulfide minerals could get effective separation. The grade of lead concentrate were increased by 0.73% and 7.89%, lead recovery were increased by 2.24% and 6.58%, and zinc recovery were increased by 4.63% and 4.19%, respectively. Meanwhile, reagent cost were all decreased by ten Yuan per ton ores in these two mines. It marks that potential adjustment flotation of sulfide minerals has been applied successfully in production practice.
